Amazon already told you the holiday fee stack. The part that will actually wreck Q4 is the inbound calendar.
What happened (confirmed)
Amazon posted its Holiday 2026 calendar in Seller Central under "Holiday 2026: Same fees, same eligibility, earlier deadlines." Fees and deal eligibility are the same as last year. The inbound dates are not.
To keep Prime-badge eligibility for the events, inventory has to arrive at Amazon facilities by these dates. Not leave the factory. Not leave the 3PL. Arrive.
Prime Big Deal Days inbound
• September 2: AWD shipments
• September 9: FBA with "minimal shipment splits"
• September 16: FBA with "Amazon-optimized shipment splits" (what most sellers select)
Black Friday Week and Cyber Monday inbound
• October 14: AWD
• October 21: FBA minimal splits
• October 28: FBA Amazon-optimized splits
Deal windows still open
• Prime Big Deal Days submissions: July 8 through September 8
• Black Friday Week and Cyber Monday: July 8 through October 20
• Early-submission discount: $50 off the upfront fee if you submitted Prime Big Deal Days deals by August 5 (that one is gone) or Black Friday / Cyber Monday deals by September 5
• Deal fees unchanged: $100 upfront per promotion plus 1.5% of promotional sales, capped at $5,000
Amazon also said Prime Big Deal Days promotional prices are excluded from the 30-day and 60-day lookback, so an October deal does not poison your November deal price.
Peak fulfillment fees still run October 15, 2026 through January 14, 2027. We already covered the $0.32 average and the 3.5% fuel surcharge stacking on top. That is not today's problem.

Why this matters
Miss the inbound date and you can still sell. You just may not have the Prime badge when the traffic shows up. That is an organic ranking problem that turns into an ads problem, then a stockout problem.
Amazon's receiving teams load in September and October, then shift to shipping customer orders in November and December. Capacity gets tighter the later you send. "We'll inbound in October" is how brands lose Big Deal Days.
The split option is a real week of runway. Minimal splits consolidates destinations and gets an earlier cutoff. Optimized splits distributes inventory up front and gets the later date. Most catalogs should take the later date unless you have a specific reason not to.
Who it affects most
• Brands still waiting on ocean freight for Big Deal Days units
• Teams using AWD (your clock is September 2, not September 16)
• Anyone who has not submitted Prime Big Deal Days deals (window closes September 8)
• Catalogs planning to inbound everything in one October dump
• Deals priced on September fees instead of peak landed cost
What CoreTrex would do this week
1. Split the calendar. Big Deal Days inventory is a September problem. Black Friday inventory is an October problem. Do not mix them into one PO.
2. Create the FBA inbound now, Amazon-optimized splits, with a receive-by of September 16 or earlier. If you use AWD, that shipment needed to be moving yesterday.
3. Submit remaining Prime Big Deal Days deals before September 8. Price them on peak fulfillment math, not summer fees.
4. Lock Black Friday / Cyber Monday deals by September 5 if you want the $50 early discount. Window itself stays open to October 20.
5. If you need extra FBA space, use Capacity Manager before receiving tightens. AWD with auto-replenishment still gets off-peak storage through October 31, which is useful if the program actually fits your cube and velocity.
Our take
The fee freeze is the easy headline. The earlier inbound dates are the actual change.
We would rather send a week early and pay a bit of storage than watch a paid deal run against a listing with no Prime badge. Freight delay is not an Amazon policy problem. It is a planning problem, and the planning window for Big Deal Days is now measured in days, not months.
Inventory still on the water, or deals not submitted? CoreTrex will map which SKUs have to hit September 16 versus which can wait for October, and price the promotions on real peak cost. Talk to a strategist.
